CONTAINER PACK.

Application filed October 22, 1923. Serial No'. 669,945.

To all 'UIZOLHL '52 may concern:

Be it known that I, CURTIS L. LYNCH, a citizen of the United States,residing at Cherryl'ield, county oi ll ashington, ,State of hilainc,have invented certain new and useful Improvements in Contain-er Packs,oi which the following is a specification.

in the n'eservation oi perishable food stuli's by sealing in closedcontainers, the canning process is greatly simplified and certainty ofpreservation greatly increased it air is excluded from the pack or itpresent is exhausted.

While the principles of preservation in vacuum or partial vacuum havebeen well understood and quite commonly practiced under various methods,the practice has been seriously limited by the expense so that domesticor small packs under vacuum have not been possible.

It is the object of my invention to provide a simple and inexpensivepack and as a basis "for such I contemplate a container or which may beof general standard characteristics, but which will make possiblepractical exhaustion after filling, wl'iereby it is possible to preserveeven. fresh fruits and vegetables'and all without added expense ordifiiculty.

Vi hile capable of embodiment in somewhatvaried forms and capable of usein a variety of methods and for almost all of the foods usually cannedor preserved, i will without sin .oration set forth only one simple formas a basis oi my disclosure. This illustrative embodiment however willreadily suggest to those skilled in the panic incart and to themanuiacturers oi preserving containers the other and more expensiveforms which. may prove justified in coin mercial use or more extendeddomestic use. 'lhroughout specification and drawings like referencecharacters are employed to designate the parts and in the drawiu Fig. 1is a central vertical section of a container in accordance with myinvention.

liig. 2 is an end view thereof. Fig. 3 is a view showing; the exhaustingstep.

Fig. l is a view showing the jar sealed, and

Fig. is a view showing a nippled cover.

in providing a container in accordance with my invention a glass yar as1 may be formed in the cover as at 4- and in both forms the nipple isprotected in its recessed position.

in connecting with the exhausting,- pump or system the end of a. tube Tcan h slipped ov r the nipple l and allowed to grip under the shoulderformed by the cup 6. Upon the removal of the tube T the cup 6 is sealedpreferably by wax or other fusiblesealing means.

Care must be taken of course in effecting his sealing without loss ofvacuum, especially since in the usual domestic pack the air exhaustionis never very complete, although with the usual simple pump sul'licientexhaustion is had for practical purposes. There is need however toconserve the partial vacuum and in order to insure this where dependencecan not be placed on the dexterity of the operator, I provide preferablyan initial sealing of the vent 5 by a. soft paraitin filling P. This maybe carried up as shown in Fig. 3 to fill the cup 6. Be fore theexhausting tube T slipped on the nipplethis filling P ispunct-ured tovent the contents; When the air is exhaust-ed the tube ll can be pulledoil with a slight lateral wiping movement of the linger which will smearover the puncture in the para'tiin and prevent the inrush of. air.

The cup 6 is preferably permanently sealed by sealing wax which may beapplied as a disc or water shoved into the cup and fused in place.

lVhen so sealed the jars will stand any normal amount of handlingand yetmay be refilled after the contents are used.

Various modifications in the form of my device may be resorted towithout departing from the spirit of my invention it within the limitsof the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. A preserving container comprising an enclosed vessel having one Wallrecessed and vented, and agnipple Within said recess; and below thesurface of said Wall, and enclosing said vent and adapted to receiveaneX- haust connection. a

2. A preserving container comprising a jar having a recessed bottom, avent throughsaid bottom, and an exterior nipple enclosingsaid vent anddisposed Within, said recess and below the bottom of the jar, and 1adapted to receive an exhaust connection.

3;:A preserving container having a recessed end With a venttherethrough, and a nipple enclosing said vent and disposed below theplane ofthe container end and 15 adapted to receive an exhaustconnection.

In testimony whereof I afiix my signature.
